Problem: We need to track environmental variables in our laboratory to identify parameters that affect our measurement results Solution: We read out sensors using Arduinos and transfer the sensor data to PCs for storage and analysis. We programmed sensors to analyze temperature, humidity, air pressure, acceleration, and motion. For some sensors (e.g. temperature sensors), the program just involves reading sensor values. For other sensors (e.g., the BMP180 pressure and temperature sensor), a library is required to handle the communication with the sensor. Some programs were written in older Arduino IDEs and they may have to […]
Scientific seminars follow ancient routines. The speaker speaks for his allocated time plus a generous 15% bonus and then the big-shots in the first row ask a few questions. But have you ever noticed that they always ask the same questions? It’s called experience, i.e., they made up their question some 20 years ago. Time for you to get up to speed and participate with your own highly original questions! Don’t have an idea what to ask? Just select one of the generic categories offered in the PDF file below, […]
Writing scientific publications seems to be a science on its own for most of young researchers, but there is no magic behind scientific writing! By following simple rules, everybody can improve his writing skills. I summarized these rules in a cheat sheet for scientific writing. Of course, you should not expect a miracle. Your principal investigator will always find something to complain about. 😉 If you want to read further on The Science of Scientific Writing, please refer to the article.

Ab initio packages for starters PCGamess: Ab initio code for your Windows PC MacMolplt: Nice visualization of Gamess output Arguslab: Visualize or draw molecules, optimize with molecular dynamics, useful to generate starting geometries Mopac: Molecular dynamics and semiempirical methods Suggested sequence for simple structure calculations: (1) Draw your molecule in CHEMSKETCH and push the ‘optimize 3D’ button, save it in .mol format (2) I used OPENBABEL to convert the .mol coordinates to Gamess input format. (3) Perform a PM3 calculation in Gamess Firefly to get a better structure (fast calculation). A […]
